-The pull rod ||4 is pivotally connected as at ||0 to the truck lever 00 intermediate the ends ofsaid truck lever, and extends over the adjacent axle and is pivotally connected as at ||0 to the live truck lever |20 intermediate the ends of said truck lever, said pull rod being preferably provided with an extension |21| extending through the pull rod guide |20 provided on'the end rail bracket |42. The lower end-of said truck lever is pivotally connected as at |22 to the fulcrum' |24 secured to the outer brake beam |20, said brake beam likewise being provided with suitable brake heads (not shown) for braking cooperation with the adjacent wheel. The brake beamj|20 is also 'supported by means of a balance hanger |20 ad- Vjacent the longitudinal center line of the truck,

th'e'upper end of said hanger being pivotallyconnected as at |00 tothe balance hanger bracket |00 tothe hanger bracket |40 provided on the` end bracket |42 of the side frame |0. The uppery end o! the live truck lever |20 is pivotally conyfnected as at |44 to thepuil rod |40, the outer end of said'pull rod being pivotallykconnected'as at |40 to the `inner end of the auxiliary lever|50. The' auxiliary lever |50 extends outwardly and downwardly and is pivotally connected inter mediate the ends thereofA as atl |52 to the automatic slack adjuster 4|54 mounted on the bracket |42 as at |00,'said slack adjuster being of suitable construction as that of the American Brake Company, and/or as 'shown in Patent No. 1,991,3330 to MltchelLgranted February 12, 1935.

The outer end of the auxiliary lever ispivotally connected as at |00 to the pull rod |00, said pullrod being pivotally .connected as' at |02 to the cylinder lever |04 intermediate the ends of said cylinder lever.`

The'upper endof thesubstantially vertically disposed cylinder lever |04 is pivotally connected v I as at |00 to the bracket |00 provided on the side trame. The lower end of saidV dead cylinder lever l 2,113,839 i vided with anti-friction rollers and are disposed is pivotally connected as at |10 to the piston rod |12 of the operating cylinder |14. The operating cylinder is suitably connected as at |10 to the depending bracket |10 provided on the end rail bracket |42 and side frame |0.

In the event it is desired to apply hand operating means to the brake arrangement this may be accomplished as indicated generally in Figure 7. In this case the pull rod |40 is provided with an elongated bifurcated end |00 adapted to receive the upper inner end of the auxiliary lever |50, said lever being loosely pivoted at |02 to the end |00 through the elongated slots |04.y The outer ends of the end |00 are pivoted as at |04 to the chains 00 which are pivoted as at |00 to the f ends of the equalizer bar' |02 which may be carried by the truck frame-or car body on suitable brackets or straps (not shown). bar is pivoted as at |04 adjacent'the center'thereof to the chain |00, the opposite end oi.' which is connected to the brake operating means 200.

Assuming the brake arrangement to be in inoperative position, when it is desired to apply the brakes, uid pressure introduced to the cylinder |14 causes the piston |12 to move toward the left as viewed in Figure 2, causing movement of the dead cylinder lever in a clockwise direction about itspivot |00. Movement of the cylinder lever in a clockwise direction causes the pull rod |00 to move the auxiliary lever |50 in a clockwise direction as viewed inFigure l, thus moving the pull rod |40 toward the right as viewed in said ligure.

AMovement of the pull rod |40 causes the truck lever |20 to pivot about the connection ||0 `to /rnove thebrake beam |20 to a position to apply its birake head and shoe assemblies to braking posit on.

. Continued movement oi' the pull rod |40 causes movement of the pull rod |4 to move the live The equalizer stai |00 of the hand toward the right causes the pull rod 64 to move' l toward the right, thus moving the live truck lever 00 in a clockwise direction about its pivot 50 to apply the brake shoesfprovided on the beam 00. Continued movement of the live truck' lever 50 causes the pull rod 52 to move the' dead truck lever 44 in a counter-clockwise direction 'to move the brake beam 30 to apply the brake shoes 40 to the periphery adjacent the wheels. Release of the actuating fluid will permit release of the brake rigging in a direction opposite to that already described, it being understood that the automatic slack adjuster is operative as by the fluid supplied to the cylinderk to take up slack in the brake system. g

It is oi' course understood that rotation of the hand operating means 200 causes the chain |00 to move the equalizer bar |92 toward the right as viewed in Figure 7, thus causing the'chains |00 to move the pull rod |46 at each side of the truck to operateA the brake arrangement in the same manner as described for the brake cylinder.

n is to be' understood that I do no: wish to be limited by the exact embodiment oi'. the device shown, which is merely by way ot illustration and not limitation, as various and other forms of the device will of course be apparent to those skilled in the art without departing from the spirit oi' the invention or the scope of the claims.
